JLA vs Galactus contest
The Justice League (past and present) vs Galactus.
To test the mettle of the JLA, the Guardians of the Universe have created a mystical pie generating machine that can produce an infinite amount of pies (any flavor imaginable.) The Guardians have called upon Galactus, devourer of worlds, as their challenger. The Guardians will observe the contest. There is to be no fighting, absolutely no cheating. No tricks like time travel, time stopping, transmuting, energy manipulation, using magic or hiding pies. ALL pies must be eaten.
Who can eat more pies?
